2 Sheets-Sheet l in cushioning stripsz23 of felt, rubber or the like, and retained by metal moldings 24 screwed to the sash as shown in Fig, '7. Thecushion strips not only make the panes weather-tight, but also absorb any harmful stresseswhich might be imparted to the glass by the intermittent flattening and bowing of the sash members, as the window is closed and reopened/ v V Each hinge pin is fastened to the sash mem ber I5 by rivets 2 5 (Fig. 9) and its depending end is formed with around head or collar 25 providing an annular shoulder 21 (Fig. 10). The head 26 is freely received in the enlarged end 28 of the slot 29 in the wall of thetube or sleeve member 2|, the latter having an integral extension 30'which is screwed or otherwise secured to the web of the T-shaped frame 22 (Fig. 12). After entering the opening 23, the pivot head slides inwardly of the sleeve 2| toward the end of slot 29, and is yieldingly held in that position with the shoulder 21 engaged underythe overhanging rims of the slotted sleeveby a stout compression spring 3| bearing on a follower 32 and retained by a screw cap 33 threading on the outer end of. the sleeve member and-adapted to regulate the compression ofthespring. m y

When the sash is closed, the springs 3i 'tend to urge and maintain the ends of sash member :5 flush against the jamb 34 of the window'framaas shown in Fig. 9, but the springs will yield while thesash is being closed so that the pintles iii may I move outwardly inthe sleeves 2!, thereby to .permit all the sash members to be fiattenedby' the clamping action of the latching device provided at the center of the free sidei3. a

The latch comprises a rotatable lever-pivoted at 35 to a plate 36 riveted to the sash side liinear its center (Fig. 11) and having a handle portion 3'5 and lockingbar 38; and a catch or hoo-k'member 39 fastened to the web of the frame 22 andhaving an inclined surface 48 terminating in a fiatface against which the barSB' bears when theflatch is moved to locking position. i It will be apparent that the cramping action .of closing the latch causes the sash member l3 to be pressed inwardly at its center, toward and snugly against the'jamb Asbest shown in' Figs. 3 to 6, the sash members 7 of the window arenormally bowedtransversely,

the degree of curvature being substantially, ex-

aggerated in' the drawings. In practice the cur vature wouldbe relatively, slight vandmerely sufficient to allow'the resilient sash members to. be

flattened against the jambupon latching the window, in accordance with the objects of this invention. The sash memberJt atxthe free side of the window is bowed outwardly at-its center with respect to the jamb; and the members l4, l5 and I8 are bowed inwardly at their centers.

- He'nce, when the window is moved toward closing position, the jamb is first engaged by thecenterof the hinged side Iii, the springs 3| of the hinge members initially. yielding as thelsash is pressed inwardly; then'th centers of the'sash ends '14 and i6 meet the jambyand finally the center of the side'lS is forced snugly against the jamb 'by'wedging the latch bar 38 toseating positionalong the inclined edgefiiii'and under the flat face 4| of the catch 38; This action not only flattens the side 13 butalso fiattensthe endmembers l4 and Hi andthehinged side i5, the ends of the latter sash members being urgedginwardly by the springs 3|. The entire peripheryof the V sash is thus firmly and tightly seated'again'st the lamb of the window frame. and held in snugengagement by'the distortion of the resilient sash members which resist any tendency to displacement until the latch is released.

A casement window constructed as herein described cannot rattle or chatter and issubstan- 'tially weather-proof when latched; yet it maybe easily opened and closed, and will swing freely on its hinge pintles. Any usual attachment (not shown) may be provided for holding the opened window in adjusted position, and it will be apparent that the improved sash may be applied to any ordinary window frame without appreciable alteration.

- As previously indicated, a bowed sash of the character just described may be employed for a door,l screen or other hinged closure shutting against a frame jamb; and-the benefits of the bowedi construction will be attainedpartially if not completely-by hinging a flat sash to a jamb which is curved relative to the plane of the meeting surfaces, or by utilizing both a curved sash anda curved jamb, so long as therelative curvature of the meeting surfaces requiresthat the center of thehinged side of the sash, the-centers A hinged closure and sash constructed in accordance with this invention ensures a, snug and tight fit between the meeting faces of the parts, withoutthe'necessity of providing special cross sectional shapes for said parts or special weather stripping to prevent rattlingor moisture, seepage.
